I've completed his quest, and now am going to wait for him to become recruitable. Does anyone have an idea how long this takes, in terms of in-game days?

first you get his dad to buy him the gear

then you hire him as a mercenary and do a job

then he's a follower/marrigeable

Thank you.

no problemo... he was supposed to become my first characters husband... I had to figure out how to go about that. LOL

So do I call you Mrs. the Slayer?

I sacrificed Erik the slayer to Botheia lol.
